NewsStudy identifies protein responsible for gas vesicle clustering in bacteria
Scientists have presented the first identification of a protein that can regulate the honeycomb patterning of gas vesicles packed within microbes.
-
NewsWild plants face viral surprise spreading from crops
A new study reveals a previously unknown threat: non-native crop viruses are infecting and jeopardizing the health of wild desert plants.
-
NewsSynthetic material could improve ease and cut cost of gut microbiome research
A team of researchers has developed a new synthetic material that could enable scientists to more easily study how microorganisms interact with the gastrointestinal (GI) system.
-
NewsMore than 18,000 excess TB cases in the U.S. attributable to structural racism
A robust analysis of national tuberculosis (TB) surveillance data found continuing, persistent disparities in TB incidence among U.S.-born racial and ethnic minorities, despite an overall decrease in cases observed during the analysis period.

NewsProbiotics in kombucha mimic fasting and reduce fat stores in worms
In a new study, researchers found that the microbes in kombucha tea make changes to fat metabolism in the intestines of a model worm species that are similar to the effects of fasting.
-
NewsTB vaccine may enable elimination of the disease in cattle by reducing its spread
Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds.
-
NewsWild nematode worms learn to avoid harmful bacteria—and their offspring inherit this knowledge
The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations.
-
NewsA combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis
Scientists repurposed approved drugs that they originally tested to normalize blood vessels surrounding tumors to improve drug delivery to cancer cells.
-
NewsMore older adults being diagnosed with STIs such as gonorrhoea and syphilis
STIs in Americans aged 55 to 64 years have more than doubled over the past decade; in England the number of over 45s diagnosed with gonorrhoea and syphilis doubled between 2015 and 2019.
-
NewsNew enzymatic cocktail can kill tuberculosis-causing mycobacteria
A new study shows that an enzymatic cocktail can kill a variety of mycobacterial species of bacteria, including those that cause tuberculosis.
-
NewsResearchers identify microbes that help plants thwart parasite
Researchers have shown that soil microbes induce changes in sorghum roots that make the plant more resistant to infection by witchweed. They identified specific strains of bacteria that trigger these resistance traits and could be applied as a soil ’probiotic’.
-
NewsImplantable device delivers HIV antiviral with more potency than oral drugs
A study shows that a nanofluidic implant delivered an HIV drug that achieved more potency than other forms of drug administration (oral) and other HIV drugs.
-
NewsNew testing approach improves detection of rare but emerging Powassan virus spread by deer ticks
Researchers have come up with a new, more accurate method for detecting in ticks the emerging Powassan virus, which can cause life-threatening neuroinvasive disease, including encephalitis and meningitis.
-
NewsResearchers a step closer to a cure for HIV
A new study demonstrates that a patented therapeutic candidate, an HIV-virus-like-particle (HLP), is 100 times more effective than other candidate HIV cure therapeutics for people living with chronic HIV on combined antiretroviral therapy (cART).
-
NewsMore than meets the eye: Researchers uncover the microbial secrets of dry eye
Researchers have used advanced sequencing technology to determine how the mix of microbes present in patients with healthy eyes differs from the mix found in patients with dry eye.
-
NewsMicroscopic sea urchin killer spreads to new species and regions
A parasite that devastated long-spined sea urchins in the Caribbean and Florida in 2022 has caused another die-off more than 7,000 miles away in the Sea of Oman.
-
NewsOnline dashboard to help fight to save children from deadly diarrheal diseases
Researchers are developing a flexible online tool for navigating information used in the fight to save children from deadly diarrheal diseases by identifying transmission hotspots and accelerating the deployment of treatments and new vaccines.
-
NewsInsights from patient who cleared hepatitis C could lead to vaccine
By studying individuals who spontaneously clear hepatitis C infections, a team of researchers has identified viable vaccine targets for a disease that infects 70 million worldwide with case numbers increasing every year.
-
NewsResearchers uncover key biomolecule involved in whooping cough infection
Researchers have identified a new complex-carbohydrate biomolecule, or glycan, that plays a key role in the nasal colonization of the Bordetella bacteria responsible for whooping cough.
-
NewsCancer therapies show promise in combating tuberculosis
A study has identified a combination of medications that may improve blood flow within granulomas, tight clusters of white blood cells formed by the body’s immune system in response to tuberculosis infection, benefiting drug delivery.
